• For reference, use SHELL type gear oil or Mobile gear oil #90.

BLADE CHOICE

Selecting the right blade for the job depends on a variety of factors, such as the type of material being cut, hardness of the material, material shape machine capability, and operator technique.
The chart is a basic starting point for choosing blade type based on teeth per inch (TPI) for variable tooth pitch blades and for standard raker type bi- metal blades/ HSS blades. However, for exact specifications of bandsaw blades, contact the blade manufacturer.
To select the correct blade TPI:

1. Measure the material thickness. This measurement is the length of cut taken from where the tooth enters the workpiece, sweeps through, and exits the workpiece.
2. Refer to the “Material Width/Diameter” row of the blade selection chart and read across to find your workpiece thickness you need to cut.
3. Refer to the “Material Shapes” row and find the shape and material to be cut.
4. In the applicable row, read across to the right and find the box where the row and column intersect. Listed in the box is the minimum TPI recommended for the variable tooth pitch blades.
5. The “Cutting Speed Rate Recommendation” section of the charts offers guidelines for various metals, given in feet per minute (speed FPM) and meters per minute in parenthesis. Choose the speed closest to the number shown in the chart.
   (The next page ”Blade Structure” is for reference only.)

BLADE CONSTRUCTION

Note : This is section is for reference purposes.
Bi-metal blade are the most commonly used. They consist of a silicon-steel backing with a laser welded high speed steel (HSS) cutting edge.
The type of stock are classified in M2, M42, M51 and differ from each other because their major hardness due to increasing percentage of Cobalt (Cc) and molybdenum (Mo) contained in metal alloy.
There are several key factors to consider in choosing a blade

• Tooth Pitch – The number of teeth per inch (TPI) on the blade.
  Select a pitch which will assure that at least three teeth are contacting the workpiece while cutting.
  This helps to distribute the cutting forces and avoids tooth breakage.

• Tooth Form – There are four common forms of teeth on the blade: Buttress, Claw-tooth, Precision and Tungsten carbide.
  Precision is the most common and is the type supplied with this saw.

• Tooth Set – Set is the degree to which the teeth are bent away from the blade.
  Typical tooth set styles are Raker, Wave and Straight set.

Always select and use good-quality saw blades and choose the right blade for the job. Discuss your cutting requirements with your saw blade dealer to make sure you are getting the type of blade which best suits your need. Poor quality blades and improper use are often the cause of premature blade failure.
Many conditions can lead to breakage. Blade breakage is, in some cases, unavoidable, since it is the natural result of the peculiar stresses that bandsaw blades are subjected to. Blade breakage is also due to avoidable causes. Avoidable breakage is most often the result of poor care or judgement on the part of the operator when mounting or adjusting the blade or support guides. The most common causes of blade breakage are:

1. faulty alignment and adjustment of the guides;
2. insufficient number of teeth contacting the cut;
3. feeding too fast;
4. tooth dullness or absence of sufficient set;
5. excessive tension;
6. using a blade with a lumpy or improperly finished weld;
7. continuously running the bandsaw when not in use

Regular Tooth:

0° rake and constant pitch.Most common form for transversal or inclined of solid small and average crosssection or pipes, in laminated mild steel and grey iron or general metal.
Positive Rake Tooth: 9°-10° positive rake and constant pitch.

Particular use for crosswise or inclined cuts in solid sections or large pipes, but above all harder materials (highly alloyed and stainless steels, special bronze and forge pig iron).

Combo Tooth:
Pitch varies between teeth and consequently varying teeth size and varying gullet depths. Pitch varies between teeth, which ensures a smoother, quieter cut and longer blade life owing to the lack of vibration.

Another advantage offered in the use of this type of blade is that with only one blade it is possible to cut a wide range of different material in size and type.

Combo Tooth:
9°-10° positive rake.This type of blade is the most suitable for the cutting of section bars and large and thick pipes as well as for the cutting of solid bars at maximum machine capacity.
Available pitches: 3-4/4-6.

Sets:
Saw teeth bent out the plane of saw body, resulting in a wide cut in the work- piece.
Regular or Raker Set:
Cutting teeth right and left, alternated by a straight tooth.

Of great use for materials with dimensions superior to 5mm. Used for cutting of steel, castings and hard nonferrous materials.
Wavy Set:
Set in smooth waves.This set is associated with very fine teeth and it is mainly used for cutting of pipes and thin section bars (from 1-3mm)
Alternate Set (in groups):
Groups of cutting teeth right and left, alternated by a straight tooth.

This set is associated with very fine teeth and it is used for extremely thin materials (less than 1mm).

Alternate Set (individual Teeth):
Cutting teeth right and left.
This set is used for the cutting of nonferrous soft materials, plastics and wood.
